Add Left Handed Mode
Give an option in the settings that lets you move the toolbar to the right of the screen for left-handed users. I am personally left-handed and I find that after animating for a while my hand starts to cramp when leaning over the toolbar to draw and trying not to rest it on the screen in case I press something I don’t want to.
It would be cool if you could switch the toolbar to the other side of the screen if you’re left-handed. I’m left-handed, and it’s a bit annoying when I accidentally tap a different tool when another part of my hand touches the screen.
